The components should be configurable independently of the global
scrcpy_options instance: their configuration could be provided
separately, like it is the case for example for some screen parameters.
For consistency, keyboard injection should not depend on scrcpy_options.
The input_manager is strongly tied to the screen, it could not work
independently of the specific screen implementation.
To implement a user-friendly HID mouse behavior, some SDL events
will need to be handled both by the screen and by the input manager. For
example, a click must typically be handled by the input_manager so that
it is forwarded to the device, but in HID mouse mode, the first click
should be handled by the screen to capture the mouse (enable relative
mouse mode).
Make the input_manager a descendant of the screen, so that the screen
decides what to do on SDL events.
Concretely, replace this structure hierarchy:
+- struct scrcpy
+- struct input_manager
+- struct screen
by this one:
+- struct scrcpy
+- struct screen
+- struct input_manager
This avoids to directly pass the options instance (which contains more
data than strictly necessary), and limit the number of parameters for
the init function.
Pass scrcpy input events instead of SDL input events to mouse
processors.
These events represent exactly what mouse processors need, abstracted
from any visual orientation and scaling applied on the SDL window.
This makes the mouse processors independent of the "screen" instance,
and the implementation source code independent of the SDL API.
Expose an option to automatically configure and reconnect the device
over TCP/IP, to simplify wireless connection without using adb
explicitly.
There are two variants:
- If a destination address is provided, then scrcpy connects to this
address before starting. The device must listen on the given TCP port
(default is 5555).
- If no destination address is provided, then scrcpy attempts to find
the IP address of the current device (typically connected over USB),
enables TCP/IP mode, then connects to this address before starting.
PR #2827 <https://github.com/Genymobile/scrcpy/pull/2827>
To allow seamless copy-paste, on Ctrl+v, a SET_CLIPBOARD request is
performed before injecting Ctrl+v.
But when HID keyboard is enabled, the Ctrl+v injection is not sent on
the same channel as the clipboard request, so they are not serialized,
and may occur in any order. If Ctrl+v happens to be injected before the
new clipboard content is set, then the old content is pasted instead,
which is incorrect.
To minimize the probability of occurrence of the wrong order, a delay of
2 milliseconds was added before injecting Ctrl+v. Then 5ms. But even
with 5ms, the wrong behavior sometimes happens.
To handle it properly, add an acknowledgement mechanism, so that Ctrl+v
is injected over AOA only after the SET_CLIPBOARD request has been
performed and acknowledged by the server.

PR #2814 <https://github.com/Genymobile/scrcpy/pull/2814>
In "adb forward" mode, by default, scrcpy connects to localhost:PORT,
where PORT is the local port passed to "adb forward". This assumes that
the tunnel is established on the local host with a local adb server
(which is the common case).
For advanced usage, add --tunnel-host and --tunnel-port to force the
connection to a different destination.

This allows to execute all adb commands with the specific -s parameter,
even if it is not provided by the user.
In practice, calling adb without -s works if there is exactly one device
connected. But some adb commands (for example "adb push" on drag & drop)
could be executed after another device is connected, so the actual
device serial must be known.
Define server callbacks, start the server asynchronously and listen to
connection events to initialize scrcpy properly.
It will help to simplify the server code, and allows to run the UI event
loop while the server is connecting. In particular, this will allow to
receive SIGINT/Ctrl+C events during connection to interrupt immediately.
The serial is necessary to find the correct Android device for AOA.
If it is not explicitly provided by the user via -s, then execute "adb
getserialno" to retrieve it.
The options --no-display and --no-control are independent.
The controller was not initialized when no display was requested,
because it was assumed that no control could occur without display. But
that's not true (anymore): for example, it is possible to pass
--turn-screen-off.
Fixes#2426 <https://github.com/Genymobile/scrcpy/issues/2426>
The input manager was partially initialized statically, but a call to
input_manager_init() was needed anyway, so initialize all the fields
from the "constructor".
This is consistent with the initialization of the other structs.
The screen may not be destroyed immediately on close to avoid undefined
behavior, because it may still receive events from the decoder.
But the visual window must still be closed immediately.
The video buffer is now an internal detail of the screen component.
Since the screen is plugged to the decoder via the frame sink trait, the
decoder does not access to the video buffer anymore.
This flag forced the decoder to wait for the previous frame to be
consumed by the display.
It was initially implemented as a compilation flag for testing, not
intended to be exposed at runtime. But to remove ifdefs and to allow
users to test this flag easily, it had finally been exposed by commit
ebccb9f6cc.
In practice, it turned out to be useless: it had no practical impact,
and it did not solve or mitigate any performance issues causing frame
skipping.
But that added some complexity to the codebase: it required an
additional condition variable, and made video buffer calls possibly
blocking, which in turn required code to interrupt it on exit.
To prepare support for multiple sinks plugged to the decoder (display
and v4l2 for example), the blocking call used for pacing the decoder
output becomes unacceptable, so just remove this useless "feature".
The screen receives callbacks from the decoder, fed by the stream.
The decoder is run from the stream thread, so waiting for the end of
stream is sufficient to avoid possible use-after-destroy.
When --no-display was passed, screen_destroy() was called while
screen_init() was never called.
In practice, it did not crash because it just freed NULL pointers, but
it was still incorrect.
A skipped frame is detected when the producer offers a frame while the
current pending frame has not been consumed.
However, the producer (in practice the decoder) is not interested in the
fact that a frame has been skipped, only the consumer (the renderer) is.
Therefore, notify frame skip via a consumer callback. This allows to
manage the skipped and rendered frames count at the same place, and
remove fps_counter from decoder.
As soon as the stream is started, the video buffer could notify a new
frame available.
In order to pass this event to the screen without race condition, the
screen must be initialized before the screen is started.
The functions SDL_malloc(), SDL_free() and SDL_strdup() were used only
because strdup() was not available everywhere.
Now that it is available, use the native version of these functions.
The size, point and position structs were defined in common.h. Move them
to coords.h so that common.h could be used for generic code to be
included in all source files.
This avoids to pass specific options values individually. Since these
function are static (internal to the file), this is not a problem to
make them depend on scrcpy_options.

The header scrcpy.h is intended to be the "public" API. It should not
depend on other internal headers.
Therefore, declare all required structs in this header and adapt
internal code.
Add a command-line option to force "adb forward", without attempting
"adb reverse" first.
This is especially useful for using SSH tunnels without enabling remote
port forwarding.
The verbosity was set either to info (in release mode) or debug (in
debug mode).
Add a command-line argument to change it, so that users can enable debug
logs using the release:
scrcpy -Vdebug
Position and scale the content "manually" instead of relying on the
renderer "logical size".
This avoids possible rounding differences between the computed window
size and the content size, causing one row or column of black pixels on
the bottom or on the right.
This also avoids HiDPI scale issues, by computing the scaling manually.
This will also enable to draw items at their expected size on the screen
(unscaled).
Fixes#15 <https://github.com/Genymobile/scrcpy/issues/15>
By default, Ctrl+C just kills the process on Windows. This caused
corrupted video files on recording.
Handle Ctrl+C properly to clean up properly.
Fixes#818 <https://github.com/Genymobile/scrcpy/issues/818>
Now that the server can access the Android settings and clean up
properly, handle the "show touches" option from the server.
The initial state is now correctly restored, even on device
disconnection.
